Letters Patent No. 113,422, dated April 4, 1871.

IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent'and making part of thesame.

To all whom it may concern Be it known that I, LEWIS GRAHAM, ofPlymouth,

in the county of Hancock and in the State of Illinois,

have invented certain new and useful Improvements in Corn-Planters anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the acccompanying drawingand to the letters of reference marked thereon making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a corn-planter, as will be hereinafter more fully set forth.

In order to enable others skilled in the art towhich my invention'appertains to make and'use the same, I will now proce-ed to describe itsconstruction and operation, referring to the annexed drawing, in which-fFigui-e1 is a plan view, and

Figure 2, a side elevation of my machine.

` Figure 3 isa bottom view showing the mode of 0perating the feed-slide.

Figure 4 is a side view of a portion of this mechanism.

A represents the frame of my machine, through which, at a suitablepoint, passes the ale B.

On this axle are placed two wheels, C C, in the outercircumference oi'which are inserted cross-pieces a, a, extending on botll sides of thewheel, and placed a regular distance apart, forming markers to show thehills.

On the inner side of each wheel C are placed cams b b, which operate, insuccession, a lever, d, hinged t on the frame A, as shown in g. 4.

This lever bears'against another lever, D, the rear end of which ispivoted on the under side of the frame, while the front end is pivotedto the feed-slide E, said slide passing through the hoppers G G and feedthe corn in the usual manner to the conductors II and shoes I, into theAground. Under the rear portion of' the frame A are placed twocaster-wheels, J J, to turn the lmachine on.

The tongue K is pivoted or hinged in the rear end of the frame, andpasses through a slotted standard, L; in fi'ont, ,to prevent any zigzagmotion, and also to regulate the depth by means'of a pin through saidstandard.

M is a foot-lever pivoted on the side of the tongue, and connected by achain, c, with the front end ofthe frame.

With my machine it requires no marking olf and saves the expense of one-hand while planting.

, lo operate the machine we will suppose the tongue is brought up tothetop of the standard L; then, by moving, it will opera-te. thefeed-bar.

In turning, press the foot-lever holding the end of the tongue up thatraises thel machine oti'of the main wheels G C and throws the weight onthe casters J J.

After turning bring the runners orI shoes I I in proper' position, andturn the wheels G G so that it is just ready to drop; relax the weight,and it is ready to go ahead.

1f, by reason of rough ground 0r accident, it should get out of line,raise-,the planter as in turning and tu19n the wheels backward orforward, as the case may require, and let down again. Y

Having thus fully described my invention,

Whatl claim as new, and desire to secure by Letters Patent, is V 1.-flhe combination of the hinged lever el and pivoted lever D and cams bb on thclwheels C C, to operate the feed-slide, substantially as hereinset forth.

2, The arrangement of the frame A with wheels C C, having cams b I1 andmarkers a a, wheels J J, levers (Z and D,.feedslide E, hoppers G G,conductors H, shoes Land the hinged tongue K, all constructed to operateas and for the purposes set forth.

In testimony thatI claim the forcgoin g I have here- -iInto set my handand seal this 4th day of February,

LEWIS GRAHAM. [n s.]
